i like the sound of the magnaflow 14815 with the resonator removed but most people swap out the catalytic converter with a test pipe but im moving to a place that has emission testing so i cant get a test pipe. are there performance catalytic converters? i dont want to buy a system, just the catalytic converter. i have an 1997 audi a4 1.8T, if i have to i can get a test pipe and just use a different address for my car.

 

There are high performance cats available in the market.

 

where can i find one?

 

A company called Labree in cali...

 

If i were you, id just get a test pipe and swap in the stock cat for testing.

 

do they do a sniffer test or obd test... i have a test pipe and don't throw a readiness code

 

So what is exactly is the difference between a high flow cat and a test pipe? And would you be able to get straight pipe from any of those two deleting the down pipe?

 

Test pipe has no flow restriction, the HFC will have some depeding on the cell count.

Test pipe

HFC

Need one let me know.

 

If i put a test pipe in my audi a4 1.8t 2002, & it throws a engine check light. who can i send my ecu to get reflashed to turn off the ECL. with out spending a ton of money?

 

Try using a spark plug spacer or 2 of them. Other places offer a J tube to keep it from coming on.

As for tuners, Unitronics offers that as a option on their tunes.
